WHEEL BALANCE ACCURACY

M1311001700300

PURPOSE

This section contains tips and procedures for 
achieving accurate wheel balance. Steering wheel 
vibration and/or body shake can result if any of these 
procedures are not carefully observed.
1. Wheels and tyres must be properly mounted on a 

balancer in order to achieve correct balance. 
Centering the wheel on the shaft of the balancer is 
essential for proper mounting.

2. Off-the-car wheel balancers must be calibrated 

periodically to ensure good balancing results. An 
inaccurately calibrated balancer could cause 
unnecessary replacement of tyres, shocks, 
suspension components, or steering components.

Check your balancer's calibration approximately 
every 100 balances. Your wheel balancer's 
instruction manual should include calibration 
procedures. If the calibration procedures specifically 
for your balancer are missing, use the generic steps 
in this section for zero calibration, static balance, and 
dynamic balance checks. The wheel balancer 
calibration checks are also described in the flowchart 
(Refer to 

P.31-7

).

PROCEDURE <Balancing Tips>

1. Confirm that the balancer's cone and the wheel 

mounting cone are undamaged and free of dirt 
and rust.

2. On this vehicle, the wheel's centre hole on the 

hub side has a chamfered edge. Use a 
back-mounting cone on your wheel balancer to 
centre the wheel on the balancer shaft.

3. Install a wheel mounting cone. The appropriate 

size cone for this vehicle is 67.0 mm.

4. Before balancing the wheel, remove any wheel 

weights from both sides. Also check both sides for 
any damage.

5. When installing wheel weights, hammer them at a 

straight (not diagonal) angle.

<Confirming Proper Balance>

1. After balancing the wheel, loosen the wing nut 

and turn the wheel 180

°

 against the balancer's 

hub. Then re-tighten the wing nut and check the 
balance again. Repeat wheel balance if 
necessary.

2. Turn the wheel again 180

°

 against the balancer's 

hub. If the wheel becomes out-of-balance each 
time it is turned against the balancer's hub, the 
wheel balancer may require calibration.

<Wheel Balancer Calibration Checks>

1. Mount an undamaged original-equipment alloy 

rim and tyre assembly (wheel) onto your 
off-the-car wheel balancer. Balance the wheel.

2. <<Zero Calibration Check>>

Loosen the balancer wing nut, rotate the wheel a 
half-turn (180

°

), and retighten the nut. Recheck 

the balance.

•

If the imbalance is 5g or less, the zero calibration 
is OK. Rebalance the wheel, then go to Step 4 to 
check static balance.

•

If the imbalance is more than 5g, go to Step 3.

3. Loosen the balancer wing nut, rotate the wheel 

1/4 turn (90

°

), and retighten the nut. Recheck the 

wheel balance.

•

If the imbalance is 5g or less, the wheel may not 
be centred on the balancer, or the balancing 
cones, the cup, and/or wing nut are damaged, 
dirty, or inappropriate for the wheel. You may 
need to refer to the balancer manufacturer's 
instructions to verify the correct attachments. 
After making the necessary corrections, recheck 
the wheel balance. If OK, then go to Step 4.

•

If the imbalance is more than 5g, the balancer 
requires calibration. Contact the balancer 
manufacturer for calibration by their repair 
representative.

4. <<Static Balance Check>>

Attach a 5g weight to the outer rim. Recheck the 
balancer. The balancer should detect 5 

±

 2g of 

imbalance 170 to 190

°

 away from the 5g weight.

•

If the imbalance is within specification, the static 
balance calibration is correct. Go to Step 5 to 
check the dynamic balance.

•

If the imbalance is out of specification, the 
balancer requires calibration. Contact the 
balancer manufacturer for calibration by their 
repair representative.

5. <<Dynamic Balance Check>>

Attach a 5g weight to the inner rim at 180

°

 

opposite the 5g weight that was added in Step 4. 
Recheck the balance. The balancer should detect 
5 

±

 2g of imbalance 170 to 190

°

 away from both 

the inner and outer 5g weights.

•

If the imbalance is within specification, the 
dynamic balance calibration is correct. The 
balancer calibration checks are complete.

•

If the imbalance is out of specification, the 
balancer requires calibration. Contact the 
balancer manufacturer for calibration by their 
repair representative.
